What is Titanium… It is a transition metal with a silver colour, low density, and high strength. Titanium is resistant to corrosion in sea water and chlorine. It’s also hypoallergenic, so it’s kind to your skin, also light weight so easy to wear.
To get these wonderful rainbow colours the titanium is anodised, adjusting the oxide level of titanium surfaces changes the spectrum of light and therefore the perceived colour of the part. The anodising is not a coating or dye, and the colour is controlled by voltage. Therefore, the properties of the base metal are not compromised during the process.
